Preliminary results of the FVS gypsy moth event monitor using remeasurement plot data from Northern West Virginia

Publications Posted on: October 01, 2008
Predictions based on the Gypsy Moth Event Monitor were compared to remeasurement plot data from stands receiving gypsy moth defoliation. These stands were part of a silvicultural treatment study located in northern West Virginia that included a sanitation thinning, a presalvage thinning and paired no-treatment controls. In all cases the event monitor under predicted the initial mortality for all stands in terms of trees per acre.

Comparison of FVS projection of oak decline on the Mark Twain National Forest to actual growth and mortality as measured over three FIA inventory cycles

Publications Posted on: October 01, 2008
Oak decline has been recorded on oak forests throughout the Ozark Plateau of Missouri since the 1970s, but severe drought in the late 1990s, combined with the advancing age of the Ozark forests, has intensified the levels of crown dieback and mortality beyond historical levels.

Western root disease model simulation versus plot remeasurement: 11 years of change in stand structure and density induced by Armillaria root disease in Central Oregon

Publications Posted on: October 01, 2008
The purpose of this analysis was to use long term permanent plots to evaluate the short-term predictive capability of the Western Root Disease Model extension (WRDM) of the Forest Vegetation Simulator (FVS) in central Oregon mixed-conifer forests in project planning situations.

Modeling bark beetles and fuels on landscapes: A demonstration of ArcFuels and a discussion of possible model enhancements

Publications Posted on: October 01, 2008
The Westwide Pine Beetle Model and the Fire and Fuels Extension were used to simulate a mountain pine beetle outbreak under different fuel treatment scenarios on a 173,000 acre landscape on the Deschutes National Forest. The goal was to use these models within ArcFuels to analyze the interacting impacts of bark beetles and management activities on landscape fuel dynamics.

Incorporating landscape fuel treatment modeling into the Forest Vegetation Simulator

Publications Posted on: October 01, 2008
A simulation system was developed to explore how fuel treatments placed in random and optimal spatial patterns affect the growth and behavior of large fires when implemented at different rates over the course of five decades.

Effects of using visualization and animation in presentations to communities about forest succession and fire behavior potential

Publications Posted on: October 01, 2008
Natural resource managers use a variety of computer-mediated presentation methods to communicate management practices to the public. We explored the effects of using the Stand Visualization System to visualize and animate predictions from the Forest Vegetation Simulator-Fire and Fuels Extension in presentations explaining forest succession (forest growth and change over time), fire behavior, and management options.

FVS and global Warming: A prospectus for future development

Publications Posted on: October 01, 2008
Climate change-global warming and changes in precipitation-will cause changes in tree growth rates, mortality rates, the distribution of tree species, competition, and species interactions. An implicit assumption in FVS is that site quality will remain the same as it was during the time period observations used to calibrate the component models were made and that the site quality will not be affected by climate change.

Vegetation simulation and our changing world: Keynote address

Publications Posted on: October 01, 2008
Prior to the 1990s, a primary focus of vegetation management on National Forest System (NFS) lands was commodity production. While the production of goods is still important, the last 20 years has seen an emphasis in the restoration of ecosystem function and resiliency. This is illustrated by a decline of more than 80% in NFS timber production since the late 1980s.

Third Forest Vegetation Simulator Conference; 2007 February 13-15; Fort Collins, CO

Publications Posted on: September 30, 2008
The Forest Vegetation Simulator (FVS) is a suite of computer modeling tools for predicting the long-term effects of alternative forest management actions. FVS was developed in the early 1980s and is used throughout the United Sates and British Columbia. The Third FVS conference, held February 13-15, 2007, in Fort Collins Colorado, contains 20 papers.
